It has been subject to a rebuild in recent years and dosent appear to smoke badly or anything like that. I dont hammer the car, but i must admit i was a little dissapointed with the performance compared to my old 2wd saph, which was about 260bhp and felt damn quick!
I see a lot of parts for sale here second hand,but i dont really know if its advisable to put them on my own car with fuelling issues etc.I like the look and idea of something like a rs500 intercooler,but i dont know if this is a bit of overkill?
I`m certainly not doing this with a blank chequebook,but i`m not afraid to spend a bit to get it right.
Really appreciate all your replies,Vaughan.
hi there, welcome to PF
as what KSA-cossie says basically; if your on a budget i would keep it simple
change the map sensor for a 3 map bar sensor, change the injectors for a set of dark greens, get yourself a decent chip (MSD would be ideal) and that's it.
the standard 4x4 intercooler will cope with 330bhp no problem, the standard turbo will be fine at 300 bhp but i wouldn't go more than 330bhp on this turbo as it might not last long depending on its condition
other things i would do is rewire the fuel pump for a direct feed from the battery; really simple to do. I would also fit a brether system as the standard one is pants. just give us a shout if you need anymore help - all this can be done by yourself its not difficult in the slightest
